Answer:
The equation of the line is
[tex]y = \frac{1}{2} x - 4[/tex]
Step-by-step explanation:
Equation of a line is y = mx + c
where m is the gradient
c is the y intercept
Gradient = 1/2
Equation of the line using point ( 4 , -2) is
[tex]y + 2 = \frac{1}{2} (x - 4) \\ y + 2 = \frac{1}{2} x - 2 \\ y = \frac{1}{2} x - 2 - 2 \\ y = \frac{1}{2} x - 4[/tex]
Hope this helps you
